5. FUNCTIONAL INSTRUCTIONS
B–61863E/15
PMC SEQUENCE PROGRAM
286
NOTE
1 The number of message number which you can display at
the same time to the alarm screen on DPL/MDI is up to 3.
2 The number of character which you can display to the
operator message screen on DPL/MDI is up to 32
characters. The message data since the 33rd character is
not displayed.
3A “~” character (code A0H) is displayed as space character
to the screen on DPL/MDI.
4 The DPL/MDI cannot display kanji (double–byte) characters.
5 In the FS15i, each alarm message must consist of up to 30
characters.
6 When using the same message number, do not set the
display request memory (A address) to 1 at the same time.
(b) You need not use numerical codes for message data input. Instead, when
programming, directly key in the characters making up the messages
(from the CRT/MDI keyboard). For the characters that CRT/MDI does
not provide for, you must enter these characters by numerical data with
special symbols “@”. For details, refer to Subsec. 5.44.6).
(c) Use external data input command (described later) where you must
combine the DISPB instruction with external data input function (for
external tool compensation, external workpiece No. search, etc.).
Such use of the DISPB instruction does not affect the interface of
external data input function though the common interface is used
between DISPB instruction and external data input function.
(d) If you write the message data items in the ROM after programming,
you cannot change them any more (they will become fixed data
items). However, you can still change and display only the numerical
data forming part of the messages if you specify addresses storing the
numerical data as the message data and assign the required numerical
data in these addresses through sequence program.
Use of this function makes it possible for you to display frequently
varying numerical data (such as tool number etc.) during automatic
operations.
(e) A message is displayed on the CNC alarm message/operator message
screen.
When using the DISPB instruction, you must satisfy the following
conditions:
To use DISPB, the optional External Data Input function or External
Message Display is necessary for CNC.
